I just made a check of characters in the guild. We have:
3 level 7
5 level 5
7 level 4
1 level 3

So it's only Joe's monk that's level 3. That one should quickly get to 4 or higher. So I don't think our spread is that big. Most characters have been online the last week so it seems you play them to get to level 4 and 5 rather quickly. E. g. with level 4-5 characters in a hard level 5 quest with 1-2 level 7 characters you can actually get more XP than usual and better loot.
